User summary: Primus was published as a series of SoundCloud recordings that provided the rules of the game as well as play samples and setting details. These audio files (apparently) are no longer available. However, the publication site does provide transcripts of the audio files available for download. Note the rules are quite light-weight and the setting is not fully developed. The files include: - Game Mechanics (3-pages) - Playing the Game (3-pages) - Setting Details (4-pages)
